So your conclusion is that Ayman al-Zawahri is dead also because he hasn't released a videotape either?
By that same token I'm probably dead as well. Because I haven't released a videotape as well.
More to the point. What purpose does releasing a videotape serve for Al Qaida aside from revealing what Bin Laden looks like, his health, and possible location to the CIA?
Lets be clear. Bin Laden never thought the USA would take Afghanistan as easily as we did. He never thought we would have such influence in Pakistan as we do now. He never thought we would control Iraq as we do now. Therefore these have been great defeats for him. One wouldn't sit back and just allow this without at least once in 3 years proving he is still in the fight. I totally agree that him being dead or alive hasn't been proven one way or the other.
And this is why Bush and Rummy have said. "if he's alive, we will get him".....enough said. But that does not then disallow others to suspect that Bin Laden is already dead...because of the lack of evidence he is alive and the lack of a coordinated defensive or offensive put out by Al Qeada since Dec of 2001.
As for Bin Laden changing his appearance...until one of these bad guys around the world is taken alive and shown to have a dramatic change of appearance I think that is all hollywood BS clouding peoples minds. His appearance won't have change much even if he is alive.
As for your comment that you haven't put out a video so you must be dead. (childish argument at best with that. No need to respond)
